The Digium Wildcard TDM400P is a half-length PCI 2.2-compliant card that
supports FXS and FXO station interfaces for connecting analog telephones
and analog POTS lines through a PC.
Using Digium'sAsterisk Open Source PBXsoftware and standard PC hardware, one can create a SOHO (Small Office
Home Office) telephony environment that includes all the sophisticated
features of a high-end business telephone system.

The TDM400P takes the
place of an expensive channel bank and brings the system price point to
a low level. By usingX100MandS110Mmodules with the TDM400P, one can create a solution with support for a
range of telephones. To scale this solution,
simply add additional TDM400P cards populated with modules.
